The Monkey Writer

With given infinite time, a monkey randomly striking keys on a typewriter will eventually produce a particulars text, such as Hamlet or even complete works of Shakespeare.

The Probability is 1/15 625 000 000, yes but not ZERO.

The successful experiment done on Infinite Monkey Theorem

In 2011, American programmer Jesse Anderson created a software-based infinite monkey experiment to test the theorem. Anderson used his own computer, working with Amazon Elastic Compute Cloud (Amazon EC2) and Hadoop. The virtual monkeys were a million small programs generating random nine-character sequences. When any sequence matched a string of Shakespearean text, that string was checked off. The project finished the complete works in 1.5 months.
